Browser Run Quick Actions now work in local development

You can now test Browser Run Quick Actions locally. Under npx wrangler dev, the browser binding's .quickAction() method runs against a Chrome instance on your machine. Before, .quickAction() worked only in remote mode, and local calls failed with The RPC receiver does not implement the method "quickAction".

Note

There are currently two limitations in the local simulation:

• The json action is emulated. It requires an AI model to extract data, and the model is not available locally, so the action returns placeholder data that matches your schema.
• The Kitesurf browser is not supported yet.

For details, refer to Test Quick Actions locally.
